2) Sundara sees a broken doll in the garbage. "Sundara fought for her breath, stumbling back against the car, pressing her head between her hands." Moni didn't really understand why she was sobbing over a doll.
3.) Grandmother thinks that the spirit of Soka's baby has taken over Sundara and is punishing her so Grandmother lights scents to get the spirit away. Soka realizes how hard she is on Sundara and feels awful about it so she sits on the end of Sundara's cot and strokes her hair.
